Laboratory experiments were conducted to evaluate different management strategies for leaf blight of clusterbean incited by Alternaria cyamopsidis during 2003 at Department of Plant Pathology, Rajasthan College of Agriculture, Udaipur. The efficacy of fungicides, botanicals and neem formulations was evaluated by poisoned food technique in Potato Dextrose Agar medium. Out of seven fungicides i.e. thiram, captan, copper oxychloride, mancozeb, carbendazim, tridemorph and tridemefon at 100, 250 and 500 ppm concentrations tested against the pathogen, at 250 ppm concentration tridemorph was found more effective to check the mycelial growth (81.01%) of the fungus and followed by mancozeb (76.87%) and copper oxychloride (71.17%). However thiram, captan, carbendazim and tridemefon were less effective. Among the five plant extracts of neem seeds and leaves, datura leaves, temru fruits, argimone leaves and mehandi seeds tested at 10, 15, 20 and 25 percent concentration. Neem seed extract gave significant results to per cent growth inhibition (63.42%) followed by neem leaf (41.44%) and Datura leaf extracts (34.12%). Out of three neem formulations, Achook (0.15%), Amrutguard (0.03%) and Nimbecidine (0.03%) tested at 1000, 2000 and 3000 ppm concentrations, at 1000 ppm concentration Achook was found more effective recording (86.31%) inhibition the growth of the fungus, followed by Amrutguard (69.03%) and nimbecidine was less effective. In general higher concentration of each treatment was more effective to reduce the mycelial growth as compared to low concentration.
